Phys.org / Egyptian farmers behind world's perfumes face climate fight alone
For years, Egyptian jasmine picker Wael al-Sayed has collected blossoms by night in the Nile Delta, supplying top global perfume houses. But in recent summers, his basket has felt lighter and the once-rich fragrance is fading.
Phys.org / Detecting neutrino trajectories in real time
Researchers hope to use neutrinos to find the sources of cosmic radiation. New algorithms out of Bochum are aiding in the search, and have also eliminated a few candidates.
Phys.org / Oil and gas air pollution linked to 91,000 early deaths in the US each year
Air pollution from oil and gas is causing 91,000 premature deaths and hundreds of thousands of health issues across the United States annually, with Black, Asian, Native American and Hispanic groups consistently the most ...
Phys.org / A new perspective on how cosmological correlations change based on kinematic parameters
To study the origin and evolution of the universe, physicists rely on theories that describe the statistical relationships between different events or fields in spacetime, broadly referred to as cosmological correlations. ...
Phys.org / Room-temperature reactor uses electrochemistry to boost nuclear fusion rates
Using a small bench-top reactor, researchers at the University of British Columbia (UBC) have demonstrated that electrochemically loading a solid metal target with deuterium fuel can boost nuclear fusion rates.
Phys.org / Dark matter in gas giants could collapse into detectable black holes, model suggests
More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside study published in Physical ...
Phys.org / Mystery Greek hominin skull dated to be at least 286,000 years old
Research led by Institut de Paléontologie Humaine is providing a finite minimum age for a nearly complete cranium from Petralona Cave in Greece that has perplexed researchers since its discovery in 1960.
Phys.org / Rising temperatures linked to declining moods around the world
Rising global temperatures affect human activity in many ways. Now, a new study illuminates an important dimension of the problem: very hot days are associated with more negative moods, as shown by a large-scale look at social ...
Phys.org / Plastics: All around us and inside us
Plastic is one of the most remarkable materials ever created. It's cheap, lightweight and endlessly versatile. It can be shaped into anything from shopping bags to lifesaving tools in hospitals, and it's clean, safe and can ...
Medical Xpress / Neural dynamics shed light on how the brain adapts to and suppresses fearful memories
Over the course of their lives, humans can sometimes acquire fear responses to specific stimuli, animals, objects or situations, typically following adverse experiences or traumatic events. Understanding the brain processes ...
Phys.org / Dark energy-filled black holes plus DESI data give neutrino masses that make sense
These are exciting times to explore the largest unanswered questions in physics thanks to high-tech experiments and very precise data. That's particularly true of dark energy, the name given to the mysterious driver of the ...
Phys.org / DNA from rainwater provides a window into tropical canopy biodiversity
Tropical rainforests still represent a treasure trove of undiscovered species. While many species of plants, animals, and insects have been identified over the years, some parts of these tropical ecosystems are difficult ...
